Answer:
The individual positive plate capacity is 85 Ah.
(D) is correct option.
Explanation:
Given that,
Number of plates = 15
Capacity = 595 Ah
We need to calculate the individual positive plate capacity in motive power cell
We have,
15 plates means 7 will make pair of positive and negative.
So, there are 7 positive cells individually.
The capacity will be
Put the value into the formula
Hence, The individual positive plate capacity is 85 Ah.
The biggest one is when we breathe from our nose and mouth
Lets take a small element of rod on it with very small size
Its total charge on rod is dQ
so we will have potential at the center of curvature due to small point charge is given as
here given that
radius (R) = a
now the potential due to complete semicircular arc is given as
we know that
now we have
